DEVICE FOR HONING AND STROPPING RAZORS.

SPECIFICATION forming part of Letters Patent No. 759,626, dated May 10,1904.

Application filed January 27,1904. Serial No. 190,776. (No model.)

. simple and effective mechanism for producing the required oval orelliptical movement of a razor or other blade over a sharpening-surface.

A further object of the invention is to provide mechanismof novelconstruction so arranged with relation to a yieldingly-supported hone asto insure the movement of the blade being sharpened over the entiresurface of the hone, thereby avoiding undue wear upon the latter and theconsequent formation of ridges or uneven places thereon.

A further object of the invention is to provide effective means forsecuring a uniform frictional contact between the blade and bone, thusavoiding uneven wear upon different portions of the sharpening-surfaceand equally distributing the weight or hearing contact throughout theedge of the blade.

In addition to the general features above outlined the inventionconsists of the novel devices hereinafter described for guiding andcushioning the moving parts of the mechanism and for preventing theaccidental displacement of the operating handle or lever while the-razoror other implement is attached thereto.

The construction of the device will now be specifically described inconnection with the accompanying drawings, in which- Figure 1 is a topplan view ofthe invention, showing a razor attached thereto in positionfor honing. Fig. 2 is a vertical section taken on the line 2 2 ofFig. 1. Fig. 3 is a detail section on the line 3 3 of Fig. 1. Fig. 4 isa section on the line 4 4 of Fig. 1. Fig.

Fig. 6 is a transverse vertical section of said plate on the line 6 6 ofFig. 5. Fig. 7 is a detail perspective view illustrating the means fordetachably securing the inner end of the operating-handle to the movablerod of the device. Fig. 8 is a perspective View of one of thesupporting-holders of the hone. Fig. 9 is a perspective view of one ofthe bracketbearings of the hone-holders. Fig. 10 is a plan view of amodified embodiment of the invention adapted for the sharpening ofsafetyrazors, and Fig. 11 is a section on the line 11 11 of Fig. 10.

The reference-numeral 1 designates a base serving as a support for thehone and operating mechanism and preferably provided with rubber feet orpegs 2. Obviously, however, a table or any other suitable support mightbe substituted for the base-board shown.

3 designates a disk pivotall y supported upon the base 1 by means of abolt 1', extending centrally through the disk and through the chase, theunder surface of-thc latter being countersunk to accommodate a nut 5,for securing the bolt 4. A flanged wear-plate 6 is interposed betweenthe base and the disk 3, as best shown in Figs. 2 and 3.

The disk 3 is formed with a vertical opening7 in rear of the center,through which ox tends a post 8, having a transversely-bored head 9 toreceive the rear end of a iftitll ld, a coilespring 11 encircling saidrod between the head 9-and a cross-pin 12, extending through the rod. Tothe opposite sides of the. lower end of the post 8 are secured the innerends of coil-springs 13, said springs'being located in a recess 14:,formed in the upper surface of the base and having their outer endssecured to the adjacent end walls of the recess 14:, Fig. 3. Thefunction of these springs is to retract and equalize the rotary movementof the post 8.

15 designates a plate resting on the disk 3 and pivotally securedthereto by a pivot screw 16. This plate is formed with stop-lugs 15 andan elongated slot 17, through which latter extends the upper end of thepivot-bolt of the disk 3, thus affording said plate a limited lateralvibrating movement without moving the disk.

Pivotally secured upon the plate 15 by a screw-pivot 18 is an arm orlink 19, having eccentrically pivoted upon its upper surface a smalldisk 20, from which projects eccentrically a pin 21, the latterextending through the rod 10.

22 designates the operating lever or handle of the device, having a bendor offset 23 adjacent to its outer end to accommodate the handle of therazor, as shown in Fig. 1. This handle 22 is detachably secured to theforward end of the rod by means of a couplingsleeve 24:, secured by aset-screw 25 to the rear end of the handle and formed near its rear endwith an L-shaped slot cooperating with a cross-pin 26, extending throughthe rod 10 to form a bayonet-joint.

1 A weight 27, having an eye extension 28, is

secured upon the sleeve 24: by a set-screw 28.

The handle 22 is provided near its outer end with a spring-clip 29,which firmly clamps the "razor-blade in position against the handle, asillustrated in Fig. 1.

The hone or sharpening device is of the rectangular shape shown and isyieldingly supported in front of the disk 3 by means best shown in Figs.8 and 9. The hone is supported in an inclined position with relation tothe disk 3, its supporting means comprising end clips or holders'30,embracing the ends of the hone, and each having an outwardly-projectingpivotlug 31, fitting a bearing-slot 32, formed in the vertical member ofan adjustable anglebracket 33,said brackets being secured at oppositesides of the base and bored to receive adjusting-screws 3 1 tofacilitate the vertical adjustment of the hone-pivots. This manner ofsuspending the hone permits it to move freely on its pivots, withtheresult that the edge of the blade being honed is always in propercontact with the surface of the hone. The stone may also be removed oradjusted without removing the bearings.

The operation of the mechanism constructed as thus described will bereadily understood.

After the razor or other blade is placed in position upon the handle thelatter, together with the rod 10, is given a longitudinal thrust againstthe tension of the coil-spring 11. The connection of the rod 10 with thesmall disk 20 bymeans of the pin 21 revolves said disk 20 as the rod andhandle are moved laterally. This lateral movement of the rod ispermitted by the pivotal movement of the arm or link 19 and plate 15.The movement of the arm or link 19 upon the plate 15 is limited by thelugs 15, and when said arm strikes one or the otherof said lugs thelateral strain is imparted to the plate 15 and through the intermediacyof'said plate to the disk 3, causing the latter to partly turn on itspivot. Thus the move- 1 ment of the operating-handle, aided by the Animportant result of the construction and relative arrangement of themechanism is that all portions-of the hone-surface are brought intocontact with the edge of the blade during the manipulation of the handleor operatinglever, and it will be apparent that the blade may be readilyreversed without detaching the operating-handle from the rod.

A distinguishing characteristic of the invention is that it avoids theemployment of gearing, belts, and crank-handles, the operation of thehandle carrying the blade simulating the ordinary hand manipulation of arazor and accomplishing the same result, but in much less time, muchmore accurately, and with appreciably less labor.

It will be apparent that when the razor is in position upon the handle22 the back and edge of the razor will bear on the stone at the sametime and the handle not come in contact with the surface of the stone atany point. It Will also be apparent that the handle 22 cannot beaccidentally disconnected from the rod, as the blade will prevent theturning of the handle to the position required for the separation of thehandle and rod, and the blade must first be removed before they can beseparated.

In the modification shown in Figs. 10 and 11 the handle 22 is straightand the springclip 29 to receive the razor-blade is located near therear end of the handle, these variations in structure being necessary toadapt the device for supporting and sharpening the short blade of theso-called safety-razor.

, I would have it understood that the invention includes, in addition tothe construction illustrated in the drawings, all such modifications andchanges in-the details as may fall within the scope of the invention asdefined by the claims.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is-
